AN INTERRUPTED OPERA

Mozart went to the opera **incognito** in Marseilles to hear one of his own works. Everything was fine… until a copyist’s mistake flipped a single note: the orchestra played **D** where Mozart had written **D‑sharp**.

To Mozart’s ear, it wrecked the harmony. He jumped up and yelled at the musicians to play the D‑sharp. The audience, thinking he was just a heckler, started hissing and shouting to throw him out.

Then he revealed who he was.

Instant reversal: “Mozart!” echoes through the house, and he’s escorted to the orchestra to conduct the rest—this time with the missing D‑sharp in place. Ovation. Parade back to his hotel.
